Abstract: A neural network processing method, device and system are provided, and the device includes: a first computing array configured to execute a first type of neural network operation; a second computing array configured to execute a second type of neural network operation, the second type of neural network operation being different from the first type of neural network operation; and a control module configured to control the first computing array to execute the first type of neural network operation, and control the second computing array to execute the second type of neural network operation. By including a plurality of computing arrays configured to execute different types of operations in a neural network, acceleration of multiple types of operations in the neural network could be achieved, and computational efficiency of a deep neural network could be improved.
